Fig. 4From: Repeated endo-tracheal tube disconnection generates pulmonary edema in a model of volume overload: an experimental studyBiological outcomes during ETT disconnect (series III). Normal pigs (n = 6), after volume overload, were randomised to either repeated endo-tracheal tube (ETT) disconnection every 15 min, lasting 15 s each (Disconnect group) or no disconnections (Control group), for 3 h. The wet-to-dry weight ratio (lung water; A) was higher in the Disconnect versus Control. BAL protein (B) and IgM (C) content appeared higher in disconnect versus control but were not statistically significant. *P < 0.05; t-test; disconnect versus controlBack to article page
